DETAILED DESCRIPTION

This disclosure relates generally to an electronic display device. Morespecifically, the disclosure relates to an electronic display devicesuch as, but not limited to, a liquid crystal display device.

In general, a shape of a liquid crystal display device may be selectedso that the device has an elongated shape. For example, a liquid crystaldisplay device may be a rectangular shape in which a length of theliquid crystal display device is greater than a height of the liquidcrystal display device. One example of elongated liquid crystal displaydevices can be found, for example, in a subway system for displayingsigns including directions. Such configurations may not include astandard size. Accordingly, manufacturing costs can be increased tocustomize each liquid crystal display device.

Embodiments described in this specification are directed to a liquidcrystal display device having a customizable shape (e.g., an elongatedrectangular shape, etc.) which may be manufactured by manufacturing astandard sized and shaped liquid crystal display device, and cutting thestandard sized and shaped liquid crystal display device according to theparticular sizing desired. It will be appreciated that such cutting canform a selected size (e.g., an elongated liquid crystal display devicehaving a length that is larger than a height, or in another embodiment,the height can be larger than the length, etc.).

When cutting a liquid crystal display device, a non-light transmittinglayer (e.g., a black matrix), may be exposed on an edge of a colorsubstrate of the liquid crystal display device. Because the black matrixmay be formed from a material having a low conductivity, but that is notan insulator (e.g., carbon, etc.), static electricity may be propagatedfrom the exposed edge. The static electricity can, for example, impactan electric field between common and pixel electrodes in a displayregion. This electric field formation can result in deterioration of theimage being displayed.

Embodiments described herein may include a plurality of slits formed inthe non-light transmitting layer (e.g., the black matrix). The pluralityof slits may cause a buffer of spacing in the non-light transmittinglayer. In an embodiment, the buffer of spacing may reduce a propagationof the electric field caused by static electricity. In an embodiment,the plurality of slits can result in a higher quality image by reducingthe propagation of the static electricity to the pixel electrodes.

FIG. 1A illustrates a partially finished liquid crystal display device10 including a plurality of liquid crystal display panels 12, 14 formedtogether, according to an embodiment. The first liquid crystal displaypanel 12 and the second liquid crystal display panel 14 may be the sameas or similar to each other, according to an embodiment. In anembodiment, there can be more than two liquid crystal display panels 12,14 on the liquid crystal display device 10. In an embodiment, the liquidcrystal display device 10 can include either the first liquid crystaldisplay panel 12 or the second liquid crystal display panel 14.

The first liquid crystal display panel 12 includes a display region 16and a non-display region 18 that surrounds the display region 16. Thenon-display region 18 may be in a frame shape surrounding the displayregion 16. It will be appreciated that the non-display region 18 may bea non-light transmitting layer such as, but not limited to, a blackmatrix. A cut line 24 is illustrated showing a location along which thefirst liquid crystal display panel 12 may be cut to form a liquidcrystal display panel having a selected size that is different from astandard size and shape (e.g., an elongated liquid crystal displaypanel, etc.).

The second liquid crystal display panel 14 includes a display region 20and a non-display region 22 that surrounds the display region 20. Thenon-display region 22 may be in a frame shape surrounding the displayregion 20. It will be appreciated that the non-display region 22 may bea non-light transmitting layer such as, but not limited to, a blackmatrix. A cut line 26 is illustrated showing a location along which thesecond liquid crystal display panel 14 may be cut to form a liquidcrystal display panel having a selected size that is different from astandard size and shape (e.g., an elongated liquid crystal displaypanel, etc.).

The first and second liquid crystal display panels 12, 14 include acolor filter (CF) substrate 25 and a thin film transistor (TFT)substrate 27. The TFT substrate 27 is larger in size than the CFsubstrate 25 such that portions of the TFT substrate 27 extend further(e.g., so that the edges of the TFT substrate 27 are visible in theillustrated embodiment) than the CF substrate 25.

A liquid crystal layer (not shown) is sandwiched between the CFsubstrate 25 and the TFT substrate 27. A backlight (not shown) radiateslight from a back surface side. The first and second liquid crystaldisplay panels 12, 14 may be supported between an upper frame arrangedon a first side of the first and second liquid crystal display panels12, 14 (front surface side of the CF substrate 25) and a lower framearranged on a second side of the first and second liquid crystal displaypanels 12, 14 (back surface side of the TFT substrate 27).

The CF substrate 25 includes the non-light transmitting layers 18, 22(black matrix) that can restrict transmission of light therethrough anda colored layer (e.g., a red color filter, a green color filter, and ablue color filter) that can transmit light formed on a glass substrate.An overcoat layer may be formed to cover the non-light transmittinglayers 18, 22 (black matrix) and the colored layer.

A pixel 82 is shown in the display region 16 and the display region 20.It will be appreciated that the display regions 16, 20 include aplurality of pixels 82 arranged in a matrix (both the length direction(left-right with respect to the figure) and the height direction(up-down with respect to the figure)). The pixels 82 are shown in ablock of three, as each pixel 82 includes a red subpixel, a greensubpixel, and a blue subpixel. The pixels 82 are described in additionaldetail in FIGS. 3 and 4 below.

Each of the liquid crystal display panels 12, 14, includes a sourcedriver 90 and a gate driver 92. In an embodiment, the source driver 90can alternatively be referred to as the source driving circuit 90 andthe gate driver 92 can alternatively be referred to as the gate drivingcircuit 92. The source driver 90 and the gate driver 92 are described inadditional detail in accordance with FIG. 3 below.

FIG. 1B illustrates one of the plurality of liquid crystal displaypanels 12, 14 having been cut to form an elongated liquid crystaldisplay panel 12A, according to an embodiment. In the illustratedembodiment, the liquid crystal display panel 12A is generallyrectangular and has a length (left-right direction with respect to thepage) that is larger than a height (up-down direction with respect tothe page). In the illustrated embodiment, the first liquid crystaldisplay panel 12 was cut along the cut line 24. For purposes ofillustration, a dashed line 32 is shown identifying an area which wouldbe occupied in a standard size of liquid crystal display panel (e.g.,the first liquid crystal display panel 12 in FIG. 1A prior to being cutalong cut line 24).

The liquid crystal display panel 12A includes the display region 16 andthe non-display region 18. Because of the cutting along the cutting line24, a cut edge 18A of the CF substrate 25 is exposed along a bottom side(with respect to the figure) of the display panel 12A. As a result, thenon-display region 18 (e.g., black matrix) is exposed at locations 18′and 18″ (e.g., a left-side and a right-side of the cut edge 18A of thedisplay panel 12A). Also because of the cutting along the cut line 24,the non-display region 18 along the bottom side (with respect to thefigure) of the display panel 12A does not include the black matrix(e.g., the non-display region 18 as in the remaining uncut sides).Accordingly, two additional regions 28, 30 are shown in the illustratedembodiment.

The first region 28 is shown in which a black image is initially set todisplay. TFT arrays are formed in an area of the TFT substrate 27overlapping the first region 28. In an embodiment, at or about 10 pixelsmay be displayed as the first region 28. It will be appreciated that anactual number of black pixels can vary above or below 10, according toan embodiment. TFT arrays are not formed in an area of the TFT substrate27 overlapping the second region 30. The color filters and black matrixare formed in an area of the CF substrate 25 overlapping the secondregion 30. Thus the color filters and black matrix are co-planar withthe cut edge 18A of the CF substrate 25.

The second region 30 may be covered by a shielding tape or the like thatshields light from transmitting therethrough. Accordingly, the firstregion 28 and the second region 30 collectively form a non-displayregion 34 that provides a function corresponding to the black matrix inthe non-display region 18 that would be present in an uncut liquidcrystal display panel (e.g., liquid crystal display panel 12). In anembodiment, the exposed locations 18′ and 18″ of the non-display region18 can propagate static electricity to the common and pixel electrodesof the liquid crystal display panel 12A.

FIG. 2A illustrates a CF substrate 40 of a standard sized liquid crystaldisplay panel (e.g., liquid crystal display panel 12 or 14 in FIG. 1A),according to an embodiment. For simplicity of this specification, FIG.2A illustrates the CF substrate 40 without a TFT substrate (e.g., theTFT substrate 27 in FIGS. 1A, 1B), liquid crystal layer, and the like.The CF substrate 40 may include aspects that are the same as or similarto aspects of a standard sized CF substrate, as shown in the CFsubstrate 25 of the liquid crystal display panel 12 in FIG. 1A. The CFsubstrate 40 includes a display region 42 and a non-display region 44that surrounds the display region 42. The non-display region 44 includesa non-light transmitting layer 44′ that restricts light transmissiontherethrough (e.g., a black matrix). In the non-display region 44, aperiphery region 44″ surrounds the non-light transmitting layer 44′ andis a transparent area, which can prevent static electricity frompropagating through the non-light transmitting layer 44′.

A plurality of slits 46 are formed in the non-light transmitting layer44′ of the non-display region 44. In the illustrated embodiment, theplurality of slits 46 is formed along a left-side of the non-lighttransmitting layer 44′ and along a right-side of the non-lighttransmitting layer 44′. In the illustrated embodiment, the slits 46 areoriented about parallel to a lengthwise direction of the CF substrate40. In such an embodiment, the slits 46 are oriented about parallel to acut edge (e.g., the cut edge 54 in FIG. 2B). It will be appreciated thatthe slits 46 can alternatively or additionally be formed on a top-sideand a bottom-side of the non-display region 44. In such an embodiment,the slits would be oriented in a direction that is about parallel to aheight direction of the display panel 40. That is, the plurality ofslits would be oriented about perpendicular to the plurality of slits 46that are illustrated in FIG. 2A.

The non-light transmitting layer 44′ includes a first edge 48 and asecond edge 50. The first edge 48 forms an outer extent of the non-lighttransmitting layer 44′ and the second edge 50 forms an inner extent ofthe non-light transmitting layer 44′. In other words, the first edge 48represents an outer perimeter of the non-light transmitting layer 44′and the second edge 50 represents an inner perimeter of the non-lighttransmitting layer 44′.

The plurality of slits 46 are illustrated as extending from the firstedge 48 to the second edge 50. In an embodiment, the slits 46 can extendentirely across the non-light transmitting layer 44′. In an embodiment,the slits 46 can extend from the first edge 48 a partial distance towardthe second edge 50. In an embodiment, the slits 46 can extend from thesecond edge 50 a partial distance toward the first edge 48. In thismanner, it is possible for the slits 46 to extend entirely across thenon-light transmitting layer 44′ or to partially extend across thenon-light transmitting layer 44′. The non-light transmitting layer 44′may function as a path of static electricity. The slits 46 may hinderstatic electricity from propagating through the non-light transmittinglayer 44′. It will be appreciated that the slits 46 may be relativelymore effective at reducing an electric field impact when the slits 46extend entirely across the non-light transmitting layer 44′.

FIG. 2B illustrates a CF substrate 41 having been cut along a cut lineof the liquid crystal display panel, according to an embodiment. Thatis, the CF substrate 41 in FIG. 2B illustrates the CF substrate 25 (FIG.1B) out of the liquid crystal display panel 12A. The cut line isgenerally selected to be between a first of the plurality of slits 46and a second of the plurality of slits 46. Similar to FIG. 1B, thenon-light transmitting layer 44′ of the non-display region 44 is exposedalong the cut edge 54. The cut edge 54 of the non-light transmittinglayer 44′ is co-planar with the cut edge 54 of the CF substrate 41. Theplurality of slits 46 is parallel to the cut edge 54.

FIG. 2C illustrates an arrangement of a color filter 56 relative to oneof the plurality of slits 46 formed in the non-light transmitting layer44′ of the CF substrate 41 in FIG. 2B, according to an embodiment. Inthe illustrated embodiment, a single color filter 56 is included. Itwill be appreciated that one or more color filters 56 can be disposed inthe plurality of slits 46. In an embodiment, the color filter 56 can bea blue color filter. In an embodiment, the color filter 56 can be acolor filter other than a blue color filter. For example, the colorfilter 56 can alternatively be a red color filter or a green colorfilter. In an embodiment, the blue color filter 56 may be preferred. Thecolor filter 56 may be inserted into the slits 46 to minimize an amountof light that leaks through the slits 46. In an embodiment, the colorfilter 56 can be a combination including one or more of a blue colorfilter, a red color filter, and a green color filter.

FIG. 3 illustrates a schematic diagram of a liquid crystal displaydevice, according to an embodiment. The liquid crystal display deviceincludes liquid crystal display panel 80 (e.g., the same as or similarto the liquid crystal display panel 12A in FIG. 1B) that displays animage, a driving circuit 90, 92 (source line driving circuit 90, gateline driving circuit 92) that drives the liquid crystal display panel80, a control circuit (not illustrated) that controls the drivingcircuit, and a backlight (not illustrated) that irradiates the liquidcrystal display panel 80 with light from a rear surface side.

In the display region 80 a (e.g., the same as or similar to the displayregion 16 in FIG. 1B) of the liquid crystal display panel 80, pixels 82(each of which is surrounded by two adjacent drain lines 84 and twoadjacent gate lines 86) are arrayed into a matrix shape in row andcolumn directions. It is assumed that the column direction is adirection in which drain line 84 extends, and that the row direction isa direction in which the gate line 86 extends. In one pixel 82, a pixelelectrode 83 is formed and the pixel electrode 83 is connected with athin film transistor 85 which electrically connects to a drain line 84and a gate line 86. The thin film transistor 85 is formed at eachintersecting point between each drain line 84 and each gate line 86.

Spacers 94 are disposed at locations at which the drain lines 84 and thegate lines 86 intersect to maintain a particular spacing (e.g., a gap)between the TFT substrate (e.g., TFT substrate 27) and the CF substrate(e.g., CF substrate 25).

FIG. 4 is a schematic view illustrating a pixel 82 including threesubpixels 82-1, 82-2, and 82-3, according to an embodiment. Subpixel82-1 is a subpixel that filters red light. Subpixel 82-2 is a subpixelthat filters green light. Subpixel 82-3 is a subpixel that filters bluelight. Each subpixel 82-1, 82-2, and 82-3 has an area that isapproximately defined by an adjacent pair of gate lines 86 and anadjacent pair of drain lines 84-1, 84-2, and 84-3.

Each subpixel 82-1, 82-2, and 82-3 has a capacitor (not shown) that iselectrically connected to the gate line 86 and a respective one of thedrain lines 84-1, 84-2, 84-3, and a common electrode 87. The capacitoris configured to generate the electrical field for controlling theportion of the liquid crystal layer for the pixel 82.

A number of subpixels 82-1, 82-2, 82-3 for each pixel 82 is based on howmany colors of filtered light the electronic display device is designedto use to form each pixel 82 in the displayed image. The ratio of 3:1 isbased on each pixel 82 being configured to have a subpixel 82-1, 82-2,82-3 for each color of light (red, green, and blue).

A black matrix (e.g., black matrix 106 in FIGS. 5A-6C) is formedoverlapping the drain lines 84-1, 84-2, 84-3 and the gate lines 86. Anupper half 102 of the pixel 82 and a lower half 104 of the pixel 82 areconnected via the drain lines 84-1, 84-2, 84-3. The drain lines 84-1,84-2, and 84-3 are oriented such that they are symmetrically angledrelative to a centerline C-C between the upper half 102 and the lowerhalf 104 of the pixel 82. The symmetrical angling of the drain lines84-1, 84-2, and 84-3 can reduce a variation in color based on viewingangles by applying a multi-domain. In an embodiment, the angling of thedrain lines 84-1, 84-2, 84-3 may be referred to as being oriented in achevron shape. The chevron shape is such that an angle α is formedbetween the upper half 102 of the pixel 82 and the lower half 104 of thepixel 82. The centerline C-C is disposed at a point in a middle locationbetween the upper half 102 of the pixel and the lower half 104 of thepixel.

FIGS. 5A-5E illustrate a portion 100 of the CF substrate 41 shown inFIG. 2B of the liquid crystal display panel 12A in FIG. 1B, according toan embodiment. FIGS. 5B and 5D include the callout A from FIG. 5A, andFIGS. 5C and 5E include the callout B from FIG. 5A. In the portion 100(FIG. 5A), the black matrix 106 is formed on a glass substrate. A part106-1 (FIG. 5B) of the black matrix 106 overlaps the drain lines 84(FIGS. 3 and 4). Another part 106-2 (FIG. 5C) of the black matrix 106overlaps gate lines 86 (FIGS. 3 and 4). An edge of the part 106-1 of theblack matrix 106 may be co-planar with the cut edge 54 of the CFsubstrate 41 (FIG. 2B). Therefore the black matrix 106 may become a pathof propagating static electricity.

In FIGS. 5A-5E, a slit 108-1 (FIG. 5B) is formed through the part 106-1(FIG. 5B) of the black matrix 106 overlapping the drain line 84 at alocation of the centerline C-C. A part of the chevron shape generallydoes not contribute to aperture ratio, as liquid crystal moleculestherein do not rotate desirably. Thus even if a small amount of light isleaked from the slit 108-1, the leakage would not generally reduce aquality of the image by much. The slit 108-1 (FIG. 5B) hinders staticelectricity from propagating through the part 106-1 (FIG. 5B) of theblack matrix 106. The slit 108-1 (FIG. 5B) can be covered by twoadjacent color filters 110, 112 (FIG. 5D). In an embodiment, the twoadjacent color filters 110, 112 may be a blue color filter and a redcolor filter. The color filters 110, 112 may be used to reduce lightleakage through the slit 108-1. In an embodiment, a green color filtermay alternatively (or additionally) be used.

Another slit 108-2 (FIG. 5C) is additionally or alternatively formedthrough the part 106-2 (FIG. 5C) of the black matrix 106 overlappingwith the gate line 86 and extending in a direction parallel to the gateline 86 (FIG. 3). The slit 108-2 (FIG. 5C) may be formed in a regionthat also overlaps with the thin film transistor. Because the part 106-2of the black matrix 106 overlaps the gate line 86 and is relativelywide, a width of slit 108-2 can be larger than a width of slit 108-1.The slit 108-2 can be covered by a color filter 112 (FIG. 5E). In anembodiment, the color filter 110 may be one of a blue color filter, ared color filter, and a green color filter. The color filter 110 may beused to reduce light leakage through the slit 108-2. Double or triplecolor filters, such as a blue color filter and green or red colorfilters may cover the slit 108-2. Because the slit 108-2 may overlap theTFT 85 (FIG. 4), at least a part of slit 108-2 (FIG. 5E) overlapping theTFT 85 can be covered by double or triple color filters.

FIGS. 6A-6C illustrate a portion 100′ of the CF substrate 41 in FIG. 2Bof the liquid crystal display panel 12A in FIG. 1B, according to anotherembodiment. FIGS. 6B and 6C include the callout D from FIG. 6A. Thepixel in portion 100′ is rotated 90° relative to the pixel in FIGS.5A-5E. In the portion 100′, the black matrix 106 is formed on a glasssubstrate, including the part 106-1 which overlaps drain lines 84 andthe part 106-2 (FIGS. 6B, 6C) which overlaps gate lines 86. An edge ofthe part 106-2 of the black matrix 106 may be coplanar with the cut edge54 of the CF substrate 41 (FIG. 2B). Because the gate line 86 is widerthan the drain line 84, the part 106-2 of the black matrix 106overlapping the gate line 86 is likely to be wider than the part 106-1of the black matrix 106 overlapping the drain line 84. Therefore theblack matrix 106 in portion 100′ may become a path of propagating morestatic electricity than the black matrix 106 in portion 100.

In the illustrated embodiment, a slit 108-3 (FIG. 6B) is formed throughthe part 106-2 of the black matrix 106 overlapping the gate line 86 andextends in a direction perpendicular to an extension of the gate lines86. The slit 108-3 can hinder static electricity from propagatingthrough the black matrix 106-2. The slit 108-3 may be formed overlappingwith a part where a TFT is not present, because the TFT is likely to beweak against light exposure. In an embodiment, the slit 108-3 can becovered by a color filter 110 (FIG. 6C). The color filter 110 may be oneof a blue color filter, a red color filter, and a green color filter.The color filter 110 may be used to reduce light leakage through theslit 108-3. Double or triple color filters, such as a blue color filterand green or red color filters may cover the slit 108-3 to reduce lightleakage through the slit 108. In an embodiment, a green color filter mayalternatively (or additionally) be used.

In the illustrated embodiments of FIGS. 5A-6C, the slits 108-1, 108-2,and 108-3 are shown on every pixel 82. It will be appreciated that theslits 108-1, 108-2, and 108-3 may be formed periodically, such as, butnot limited to, every two or three pixels.
